摘　　要：针对反渗透隔膜增压泵的振动噪声问题,应用消声室、振动测试平台,以400G大通量四腔室反渗透隔膜增压泵为研究对象,通过额定工况下的噪声测试、变转速激励振动测试以及2.5°,2.8°,3.0°三种不同偏心轮角度下的振动测试,获取反渗透隔膜增压泵振动噪声信息,并开展频谱分析、特征比对,结果表明:设备噪声声压级最大位置位于出口端,为45 dB;反渗透隔膜增压泵运行状态下振动及噪声优势频率的中心频率在4倍轴频80 Hz;泵主振动、噪声诱发因素为腔室内液体压力冲击壳体、管线及凸轮支架的惯性冲击。所得结论可为反渗透隔膜增压泵的低噪设计提供理论技术支持。In order to solve the vibration and noise problem of reverse osmosis diaphragm booster pump,anechoic chamber and vibration testing platform were used to take 400G high-flux four-chamber reverse osmosis diaphragm booster pump as the research object.Through noise test under rated working condition,variable speed excitation vibration test and vibration test under three different eccentric angles of 2.5°,2.8° and 3.0°.The vibration and noise information of reverse osmosis diaphragm booster pump was obtained,and the frequency spectrum analysis and feature comparison were carried out.The results show that the position of maximum sound pressure level of equipment noise was located at the outlet,which is 45 dB.The center frequency of dominant vibration and noise frequency of reverse osmosis diaphragm booster pump is 80 Hz in quadruple axial frequency.The main factors of the pump by induced vibration and noise are the inertial impact of liquid pressure impacting the shell,pipeline and CAM bracket.The conclusion herein can provide theoretical and technical support for low noise design of RO diaphragm booster pump.
